<p>A surface treatment device that comprises a burner and an impaction chamber that encloses the flame of the burner. Temperatures in the impaction chamber are controlled such that the temperature of the flow of particles at the elongated outlet opening is lower than 70 % of a bulk melting point of the particles. The impaction chamber is further dimensioned to reduce the cross-sectional dimension of the flow towards an elongated outlet opening of the impaction chamber. Probability of the desired surface treatment processes to take place increases and better spatial distribution of particles in the treated areas is achieved.</p> |
